Can the N3DS Sell More than the Vita Lifetime in Japan? If Not Can It Temporarily Surpass It?

[POE]

No. The N3DS will have 1 year at least before the new handled will be released (I think Nintendo will announce it at the E3) and PSVita will have another 2 or 3 years or more, everything depends on the power of the new Nintendo handled.

How can you possibly believe that nintendo will announce a new handheld 5 months after releasing the new3ds??
